Brendan Rodgers has said he wants to add 'three or four' new faces during the close season and has reiterated that he will strengthen again to get the club into a position to challenge the top four.

'We are hopeful that come the summer we can make the additions that will take us on to the next level,' said Rodgers, during an interview with Yahoo!
